This invention relates to outletsfor containers,

and more particularly for collapsible tubessuch as are used formarketing tooth paste, shaving cream and othercosmetics and compositionsthat are of a pasty consistency, and to means for closing and openingthe outlets-for such containers. The object of outlet and means forclosing and opening the same by a valve-likedevice that will take theplace of and collapsible tubes which are formed with a screw threadeddischarge orifice of their own.

inexpensive device for charge outlet which cannot be removed from thecontainer; a device which can be quickly and easily opened and closed,which when closed will perfectly seal the outlet and which when opened,will permit the paste to be expelled from the tube easily and in a cleanand convenient manner.

I attain these and .other objects, as hereinafter described and asillustrated in the accompanying drawing, in which:--

Figure 1 shows an ordinary form of a cream paste tube having a dischargeoutlet through a small globular extension head instead of the screwthreaded extension now shows a dome-like cap designed to be fitted onand around the globular extension; Fig. 3 shows the cap set in place,and Fig. 4 shows the cap crimped in' place on the globular extension,thus securely closingv the outlet; Fig. 5 shows a top 4; Fig. 7 is a topview of Fig. 6; andv Fig. 8 shows the cap turned to the position foropening the discharge outlet.

Each of these figures is approximately full size.

Figures 9 and 10 are enlarged vertical central sections of Figs. 6 and 8respectively; and Figs.

5 has a milled annular reinforcing rib 6 at its base as seen in theseveral figures. ing 1 extends downward from this base rib. with anopening 8 in one side sufiiciently wide to freely permit a rotatingmovement after the cap is fitted in place on the globular extension head3,

In 5 the cap'5 and directly opposite the opening 8 ismade a hole 9 corresponding in size with the outlet opening 2 which isdesigned to register, with the same when the cap is rotated to one sideas shown in Figs. permit the paste within the tube '4 to be easily.pressed out till the desired amount is obtained and"v used.

tion-of the invention. It is to be observed that there is no limit as tothe form and size of the discharge outlet 2 and the hole 9. They may beround, square, oblong go or rectangular in section whereby any desiredmay be secured. It is to be observed that the skirting 1 around the neck4 and the lower part of the head 3 will be 'suflicie-itly elastic to letthe cap 5 be easily rotated thereon, but will also hold the samesecurely in place and insure a perfect seal forthe I tube outlet. It isalso to be observed thatthe milled annular rib 6 willprovide a gripsurface whereby the cap can be easily rotated to one side and back againas described. It is to be further observed that the cap beingspherically mounted on the head 3 will be self pivoted and self centeredand the hole 9 will always register with the tube outlet 2 when rotatedto the proper angle as shown in the drawing. And'furth'er, it willbeseen. that the cap in place will be spherical in form and there will beno liability of its being rotated by any ordinary contact, such as beingpacked in a traveling bag and the like.

The outlet head and cap may be madefrom any suitable metal now commonlyused in the manufacture of paste tube outlets. The construction ispurposely made of the most simple form so as to be cast and stamped inquantity production. The invention provides a well known need in thatit-will do away with the tedious screwcaps now in general use forclosing paste tube outlets.
